In June I visited the Turda Salt mine complex in Cluj county, Romania. The salt was deposited 13.6-13.4 million years ago during the middle Miocene. Mining here was first noted in 1075 AD, but was thought to have started much earlier. The mine complex closed in 1932 but was re-opened as an underground theme park in 1992. As well as awesome patterns in the cavern walls to wonder at, you can play table tennis, pool, mini golf, ride the Ferris wheel or be entertained in the 180 seat amphitheatre. Best of all, you get to boat round the underground lake formed when the Terezia mine flooded and see the amazing layers and folds in the salt close up!
